[CALCITE-4789] Build is broken on Guava versions < 21

Fix build for Guava 19.0.

In Travis, test oldest and newest supported Guava versions.
(Previously we were only testing against the default Guava
version, 29.0-jre, and that's why we didn't notice the build
breakage.) Enable ErrorProne only on the newest Guava
version (because sometimes we use APIs that are marked Beta
in early versions and the Beta is removed in later versions).

Allow Guava version up to 30.1.1-jre. Lowest Guava version
is still 19.0. Default version is still 29.0-jre.
